of the packet, use "pi.captured_len" - "fd->pkt_len" may include data
that isn't in the capture, due to a short snapshot length.
Don't use "fd->cap_len" when checking to see if you've run off the end
of the packe, use "pi.captured_len" - "fd->cap_len" isn't adjusted to
reflect any length fields, but "pi.captured_len" is (removing, for
example, Ethernet padding from the packet).
Use "END_OF_FRAME" rather than "pi.captured_len - offset", to make it a
bit clearer what's being done.
In the V.120 dissector, use "tvb_length()" when adding the top-level
protocol tree entry for V.120, as it's a tvbuffified dissector.

a particular type, rather than taking a varargs list, along the lines of
the "proto_tree_add_XXX_format()" routines.
Replace most calls to "proto_tree_add_item()" and
"proto_tree_add_item_hidden()" with calls to those routines.
Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to
"proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and
add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()"
routines that don't take the item to be added as an argument - instead,
they fetch the argument from the packet whose tvbuff was handed to them,
from the offset handed to them.

Add exceptions routines.
Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as
the tvbuff_t* argument to proto_tree_add_*() routines.
dissect_packet() creates a tvbuff_t, wraps the next dissect call in
a TRY block, will print "Short Frame" on the proto_tree if a BoundsError
exception is caught.
The FDDI dissector is converted to use tvbuff's.

registration routines to get rid of the special handling of ONC RPC
protocols - dissectors for ONC RPC-based protocols should register their
protocol, fields, and ETT values in a protocol registration routine, and
register themselves with the ONC RPC dissector in their protocol handoff
routine, so that the latter is done after the ONC RPC dissector's
protocol registration routine is called, so that the data structures
needed when dissectors for ONC RPC protocols register themselves with
the ONC RPC dissector have been initialized.
Get rid of "init_dissect_rpc()", which initializes said data structures;
do that in "proto_register_rpc()" instead.

handle data (snoop does this, and it's somewhat convenient if you're
trying to see whether, say, an ACCESS call is acting on the file whose
file handle you got back from a previous MOUNT request).
Boost the maximum number of bytes worth of hex data shown by
"bytes_to_str()" from 10 to 16, so that we can show the file handle 16
bytes per line (as snoop does).

If using GCC 2.x, we can check the print-format against the variable args
passed in. Regardless of compiler, we can now check at run-time that the
field type passed into the function corresponds to what that function
expects (FT_UINT, FT_BOOLEAN, etc.)
Note that proto_tree_add_protocol_format() does not require a value field,
since the value of a protocol is always NULL. It's more intuitive w/o the
vestigial argument.
Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c
Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*)
Checked in Guy's fix for the function declearation for proto_tree_add_text()
and proto_tree_add_notext().

non-null, it returns through that argument a pointer to the displayed
version of the string, otherwise it just frees that string.
Use that to put, in the tree item for READDIR and READDIRPLUS reply
directory entry items, the file name from the directory entry.

dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:
obviates the need to update "packet.h" whenever you add a new
subtree type - you only have to add a call to
"proto_register_subtree_array()" to a "register" routine and an
array of pointers to "ett_", if they're not already there, and
add a pointer to the new "ett_" variable to the array, if they
are there;
would allow run-time-loaded dissectors to allocate subtree types
when they're loaded.
